Join us for CeeD's monthly meeting with Professor Andrew Hursthouse on the topic of critical thinking in waste and resource management. Learn about industrial ecology and the systems approach to designing industrial products and processes. Discover how life cycle analysis and waste management can contribute to sustainability. Don't miss out!

Critical Thinking in Waste and Resource Management Professor Andrew Hursthouse School of Science andrew.hursthouse@uws.ac.uk
Industrial ecology and the systems approach “an approach to the design of industrial products and processes that evaluates such activities through the dual perspectives of product competitiveness and environmental interactions“ From Graedel, TE & Allenby TE, Industrial ecology and sustainable engineering, I.E. Pearson, Boston , 2010 ISBN: -13: 978-0-13-814034-2
Life Cycles & Waste • Life cycle analysis: • Resource acquisition and processing; • Manufacture; • Use; • Re-use/ recycle, disposal • Hidden resources and positioning new products? • Defining endpoint options? • Boundary definition and scope • Benefits accrued • Efficiency, safety, quality, expectations
LCA Methodology: new formulations in cultural heritage • Cradle to Gate • New chemical routes • Green production process • Gate to Grave • Conservation process • Social issues in cultural heritage
Drill cuttings and fly-ash in ceramic applications • Diversion of solids from landfill • Drill cuttings from oil exploration • Reclaimed de-inking sludge fly ash • Stable high silicate materials, variable composition 1200 oC
Detail of glaze derived from reclaimed ferrous sulphate rich de-inking sludge fly ash - vitrified, stoneware appearance, good glaze ‘fit’ & low-fired to 1200°C (Energy saving 80-100 °C) Clear division between commercial stoneware tile substrate & SFA recyclate glaze, showing glassy phase/matrix (x100) = Vitrified & fused Glaze Substrate
Steel Processing By-products • High zinc (+ other potentially toxic elements) in sludge from APC restricts disposal options • Annual Steel production 116Mmt (2011), = 600-1,200kg/mt waste. Variable in composition. • Can better chemical characterisation be used to improve handling and classification? • buffered to environmental change • Identification of distribution between reactive phases
Approach • Develop cost effective, reproducible (analytical) methods to enhance characterisation • Can now define reactivity depending on solid phase association • E.g. ZnO v ZnCl2 v ZnS • Develop understanding through targeted chemical extraction • Strong influence of sample variability
Emerging Waste activities • Biofuel from waste biomass – with Hamburg University of Applied Sciences • Microbial treatments for WEEE: Harvesting promising micro-organisms from “stressed” environments
Centre for Environmental Research • Waste and pollution management; materials characterisation and behaviour; adaptation and climate change; ecosystem health; policy implementation & decision support. • Centre for Environmental & Waste Management • MSc/PGD Waste & Clean Technology, Project Management • BSc OSH, Environmental Health andrew.hursthouse@uws.ac.uk

Waste (Scotland) Regulations Robin Stevenson - Managing Director William Tracey Group
Time has run out !!!!!! ARE YOU COMPLIANT ?
Waste (Scotland) Regulations Key Points • Waste (Scotland) Regulations were passed by the Scottish Parliament on 9 May 2012 • Came into force on the 1st Jan 2014 • WTG signed up to adopt regulations 6 months early as part of Scotland’s 2020 Climate Change Group • Affects all businesses, local authorities and waste suppliers • Metal, plastic, glass, paper, card and food must be segregated and collected separately for recycling. All the above separately collected materials will be banned from Landfill or Incineration from the 1st January 2014 • Ambitious 70% recycling rate target for waste produced by households and businesses by 2025
Waste (Scotland) Regulations What should l be doing ? • You MUST separate out the following from your waste stream from the 1st January 2014: • Separate out your Food waste(if you produce more than 50kgs (down to 5kgs per week from 2016) • Segregate out your Glass (Clear is more valuable) • Segregate out your Dry mixed recyclates (EG:Card/Plastic/Paper/Cans/Cardboard) • The above MUST be collected and treated separately by your contractor
Waste (Scotland) Regulations What if l do nothing ? • You Waste will NOT be able to be collected by ANY contractor • You may be prosecuted under the Waste (Scotland) Regulations £10,000 per fine • Economic drivers such as Landfill Tax - now at £72 per tonne rising to £80.00 per tonne in April this year • You will incur additional costs to collect contaminated loads • Green credentials / PR and possible requirements (Scottish Tourist Board) • Unsightly build up of waste whilst an alternative solution is found
Waste (Scotland) Regulations What have William Tracey done to help their customers ? • Huge investment in ‘POD’ vehicles collecting multiple waste streams • Huge reduction in carbon footprint • Latest eco friendly engines – Stop Start facility fitted to each truck • Huge reduction in the number of trucks & collections at site in cities & towns
Waste (Scotland) Regulations What have William Tracey done to help their customers ? Colour Coded Lids and dual Recycling Bins GLASS FOOD GENERAL MIXED RECYCLING
Waste (Scotland) Regulations What have William Tracey done to help their customers ? • Less bins improving the aesthetics • Makes it easy to segregate and to use • Further reductions on vehicle movements • Further carbon footprint reductions
Waste (Scotland) Regulations What have William Tracey done to help their customers ? • We have sent our Zero Waste Scotland booklet to everyone of our customers • We have trained all our staff including all our drivers on the new regulations so they can help and advise our customers on the changes they need to introduce to meet the new regulations • We have held free seminars for all our customers to come along and listen and gain advise on the new regulations and another one planned in February • We have had a 9 month advertising campaign in the national press
Turning Waste into a Resource OUR FACILITIES
Turning Waste into a Resource Our MRF’s • Mixed recycling is separated into various streams which are then baled and shipped to manufacturers who will go on to use your waste to manufacture products like newspapers, toilet roll and packaging products!
Turning Waste into a Resource Anaerobic Digestion • We turn your food waste into renewable energy • AD is natural process which results in the creation of a Biogas (a mixture of methane and carbon dioxide) and a digestate which can be used as organic fertiliser • The Biogas generates renewable energy sold to the national grid and the fertiliser is used in agriculture
Turning Waste into a Resource RDF- Refuse Derived Fuel • We offer our customers a genuine zero waste opportunity • RDF processes and bales residual waste • Waste is baled and sent to facilities where it is used to generate renewable energy • Zero waste to landfill business
Breaking Barriers Change how you think about waste • Your waste is a resource • Remember the regulations can create opportunities for your business: • Compliance- be more prepared than your competitors • Cost- start controlling costs now • Environment- enhance your CSR
